Agree......Uncle Sugar was teaching the Gracie Bro’s 7 basics in the late 80’s to some of us. Aikido was to that point my choice. Now Krav Maga is a favorite for me in my old age if my handgun carried fails me for some unknown reason........hopefully !
Wing Tsun Kung Fu is good for an older or smaller person, but it's not good in sport fighting. If you combined the BJJ and Sambo ground techniques with Krav Maga and Wing Tsun, you probably wouldn't need to torture yourself with the Muai Thai training (OUCH).
Truth is, a fighter trained in a style like Shotokan - very primitive and fairly useless as far as I'm concerned, can still kick the snot out of untrained fighters.
I spent 8 years learning Karate, Judo, Tae Kwon Do and more before finding Wing Tsun Kung Fu. It doesn't look at all like the fighting they do in films. Finally, arrived at MMA - a distillation of the deadliest techniques.
Some of the grappling I learned in Kung Fu was the same that I learned in Krav Maga.
